high technology and high quality

CTVM manufacture high-voltage hermetic glass-to-metal feedthroughs, either standards or custom-made.  Our products are designed for applications in the fields of vacuum, high-vacuum, high pressures, cryogenics and high temperatures.

Magnetic versions are built with a Kovar lead and sleeve. Non-magnetic versions are built with a stainless steel sleeve and a molybdenum lead.

Two standard ranges of feedthroughs are available :

  • Feedthrough type 102 – Insulation > 10 12  Ohms and flash-over resistance from 10 to 20 Kv – sleeve diameter 6 – 8 – 10 mm – lead diameter 1 to 2 mm
  • Feedthrough type 103 – Insulation > 10 10 Ohms flash-over resistance from 2 to 15 Kv – sleeve diameter 4 – 5 – 6 – 8 -10 mm – lead diameter 1 to 4 mm
